A container with insulating walls is divided into equal parts by a partition fitted with a valve. One part is filled with an ideal gas at a pressure P and temperature T, whereas the other part is completely evacuated. If the valve is suddenly opened, the pressure and temperature of the gas will be:

A

`P/2,T/2`

B

`P,T`

C

`P.T/2`

D

`P/2,T`

Text Solution

Verified by Experts

The correct Answer is:
D

It is the free expansion
So, Tremain constant
`P_(1)V_(1)=P_(2)V_(2)`
`PV/2=P_(2)(V)`
`P_(2)=(P/2)`
So, correct choice is (d)

Show that the volume coefficient of on ideal gas at constant pressure equals T^(-1) where T is the absolute temperature

Two cylinders A and B of equal capacity are connected to each other via a stopcock. A contains a gas at standard temperature and pressure. B is completely evacuated. The entire system is thermally insulated. The stopcock is suddenly opened. Answer the following : (a) What is the final pressure of the gas in A and B ? (b) What is the change in internal energy of the gas ? (c) What is the change in the temperature of the gas ? (d) Do the intermediate states of the system (before settling to the final equilibrium state) lie on its P-V-T surface ?
